Classification of Diverticular Cells of the Midgut Gland in the Prawn Penaeus japonicus クルマエビの中腸腺盲管細胞の分類 NAKAMURA, Kaworu 中村, 薫 open access Histological observation was undertaken with the light and electron microscopes for the diverticula of the midgut gland in the prawn P.japonicus. Epithelial cells except for the distal portion of the diverticulum were classified morphologically into three typed cells, light, dark and vacuolated. At the end area of each diverticulum, undifferentiated cells were distributed. After 30 days of starvation, the cavity in the midgut gland developed enlarged openings of primary and secondary diverticula which suggesting a drastic change of the construction. Further, a cellular transition from the light cell to the vacuolated cell was indicated in the result of computing estimation concerning the distribution frequency of each typed cell. It was deduced that the light cell was transformed to the vacuolated cell under a critical condition such as long-term starvation. 鹿児島大学 Kagoshima University 1987-12-25 eng departmental bulletin paper VoR http://hdl.handle.net/10232/13361 https://ir.kagoshima-u.ac.jp/records/7873 0453087X AN00040498 鹿児島大学水産学部紀要 Memoirs of Faculty of Fisheries Kagoshima University 36 1 207 213 https://ir.kagoshima-u.ac.jp/record/7873/files/AN00040498_v36-1_p207-213.pdf application/pdf 1.6 MB 2016-10-28 1987-12-25
